To all whom it may concern:

Be it known that I, WALTER MoRRIs'0N,-.

a citizen of the United States, and a resi-- dent of the city of Canton, in the county of Stark and State of Ohio, have invented a new and useful Improvement in Machines for Closing In Roller-Bearing Cages, of which the following is a specification.

My invention relates to machine forclosing-in the cages of roller bearings, whereby the cages are changed from a bowed condition to conical form, so as to properly retain the conical rolls in position on the cone or inner bearing member. The invention has for its principal object a machine that is simple and easy to operate and that has few The invention parts to get out of repair. consists principally in mounting a plurality of fingers in radially extending slots in a die and providing a reciprocating member; adapted to engage the ends of said fingers to force them inwardly against the cage ofa roller bearing disposed centrally thereof. The invention furtherioonsistsin the machine and in the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawing which forms part of this specification and wherein like reference characters indicate like parts in the several views,

Fig. 1 is a top plan view of a closing in machine embodying my invention, a portion being broken away, so as to show certain part in horizontal section, a V f Fig. 2 is a vertical sectional view, a portion of the upper member of the device being shown in elevation, and

Fig. 3 is a sectional view similar to Fig. 2 showing the operating fingers in their outermost positions and a cage in bowed condition. I

A suitable die 1 is provided with a central depression that is adapted to receive an assembled roller bearing cone 2, rolls 3 and cage 4:. In order to permit the rolls to slip, over the rib on the end of the. cone and into the cage pockets. the cage is bowed out-' provided withradially entending slots 6,;i1i

each offndiich is dispOSeda-fingenT that has its inner end: beveled or inclined 'to conform to the inclination desired for the Qbri'dgesf spaced: to confergn 5'off'the cage .4 of the roller bearing? The fingers are angularly to the spacing of the bridges of. the cage. 1

Secured "to'ftheYtop' ,of the ;die.'1, 3 as by screws .8, is a' "retaining .Tings}? that is. provlded with an annular-slot-lQ'on the under,-

side thereof; Each finger K has a projecting lug 11 that extendsfintosaid'slot- 10. "Thus,

the' strollre'of the fingers-7 isl-ir'n'ited and the ing ring 91 3 v A plunger 12 is. disposed above the die 1. The enlargedhead 13 of 'sa-id plunger is provided with a conical socket 14 therein. Theouter ends 15 ofthe cage closing fingers 7 are beveled-or inclined to cooperate 'lwith the conical surface of th socket 14 of the plunger 12; and as the plunger descends, the fingers 7 are forced inwardly by the action of the conical portion 14 of ,the plunger against the inclinedaends 15 of the fingers 7 The operation of the device is as follows: The assembled roller bearing is seated in the central depression in the die so that each bridge 5 of the bearing cage 1 is in alinement with one of the fingers 7 Then the plunger is lowered and as it engages the ening the bridges and closing in the cage.

Obviously, the stroke of the fingers 7 may be adjusted to any desired length merely by varying the stroke of the plunger.

Ordinarily, the edges of the bridges of the cage are broken down or. winged prior to the assembling operation. At times, however, the cage may merely .be perforated, the bridges remaining substantially rectangular in cross section. In such case, the bridges are forced against the sides of the ro lers and are shaped to the rollers by the closing in operation.

The herein described machine is simple and easy to operate. As shown in the draw ings, the roller bearing'is seated in the die with its small end uppermost; and as the bearing is removed from the die, the fingers are forced outwardly. This makes it unnecessary to provide stripping springs to force the fingers outwardly; but, of course, such fingers cannotube removed from thedieexceptby unscrewing and removing. the retainsprings may beused', if desired. lit the cage were seatedin the die with the bearing disposed with its large end uppermost, it might be desirable to use such stripping spriings, although they would not be essentia My fixture has very few parts and those parts are strongly built and not likely to get out of order. in case one finger breaks, itfcan easilyvbe replaced. Obviouslymw nierous changes may be niade "withotat departing frointhe invention; andl do not wish: to be limited to theprecise construction shown- What I; claim is:

ingc'ages comprising a die having a central depression adapted to receive a con cal roller hear1ng,' a plurahty of fingers mounted in said die, said fingers being angularly spaced to conform to the spacing'of the bridges of the'cage of the roller bearing, and a plunger for operating on the outer ends of said fin-. gels to force them radially inwardi agalnst the bridges of the cage. 1;, I

2. A machine for closing in roller hearing cages comprising a die having a central depression adapted to receive aconical roller bearing, a plurality of fingers disposed in said die saidjfingers having in ,clined outer ends, said fingers being, angularly spaced to conform to the spacing of the bridgesoi the cage of the roller bearing and a hun er havin a conical de ression therein adapted to engage the inclined ends of said fingers to operate them;

4. A machine for closing in roller bean ing cages, comprising a die having a central depression adapted to receive a conical roller bearing, a plurality of fingers dis posed in slots provided therefor in said die, said fingers being angularly spaced to con form tothe spacing of the bridges of the cage of the roller bearing, a ring secured to the top of said die, said ring having an annular slot in its under surface, said'fingers being provided with lugsthat extend into said slot, and means for operating said fingers I Signed at Canton, Ohio, this 14 day or": April, 1924:.
